Customer Ratings & Reviews

I love the product I only wish you offered free shipping more often .

i have use amsoil for the last 20 years had a 7.3 d for 15yrs. had 360.000 miles on it when i sold it and not one oil problem with it . your oils gave me better all around performance and i still use it in all my vehicles to this day.

I have used this oil in my 2008 Toyota Prius since November 2015. There was a noticeable improvement in gas mileage. I consistently get 52 to 54 MPG. My Prius has 183.000 miles and it runs better than new. It does have higher oil consumption than when I used petroleum based oil, but it hasn't impacted the performance. It should help the engine last a long time.

Our 1999 Odyssey wouldn't start after our son pulled off the highway to tighten down the tarp on the trailer he was towing. By the time the tow truck driver got there, it did start. The driver said he would follow for a time to insure the van kept going before he went on. The engine temperature immediately jumped into the red zone. An inspection showed that the rusted hose clamp at the bottom of the radiator had given up--there was nothing in the cooling system! After a tow to the shop, with the addition of a new clamp and coolant, the vehicle started. 1300 miles later, we heard about this from or second son and our mechanic checked for codes. The sensor had recorded 395F at the time of this incident! I immediately replaced the crank oil for 5 new quarts of Signature Series 5W-30. The old stuff, which only had a few thousand miles on it, smelled just slightly burned. Our mechanic said he would typically expect the engine to be toast, with vital components even melted! Yet, although we don't know the actual condition of the rings, pistons and cylinder walls, the car is running well, with no misses or apparent loss of power. The only reason we can all think of for survival of the engine is the Amsoil, with its superior cooling qualities. It gets the credit for the fact that the engine is still running at all!

Like title says! They do! I buy this stuff by the gallon case. We have 4 newer Hondas that use 0w20. I still change oil every 5000 miles. Honda and Amsoil say you can longer but my OCD won't let me go past 5000!!!!

I use the 5W30 in 2 of my cars, 1 Chevy truck, and 2 Street Rods. In fact I use Amsoil in everything from my air compressors to my boats. Never thought of using any oil but Amsoil since the mid 70's. I'm a walking advertisement for Amsoil... great oil, in fact I just turned 325,000 miles on my motorcycle, if that isn't proof of Amsoil then I don't know what is!

Best oil period

2002 Ford Ranger, 598,898 original miles. V6. Amsoil Filter and Oil. Still running strong. Dirt bikes, tractor, and 3 other vehicles,......I never used an "additive".....only fluids going in my vehicles are AMSOIL!!!!!!

I have used most of the major brands of synthetic oils out there in my pickups, cars and motorcycle, both gas and diesels . The increased oil change intervals alone make Amzoil signature series oils worth it. Just gage the oil changes using the on board computers and you will see the difference . Every other premium synthetic lasted approximately 6,000 to 7,000 miles going down to 5% life left. Amsoil goes over 10,000 miles on every oil change at 10% life left. defiantly a superior oil.

I use amsoil in everything I own bikes quads vehicles ect. I use this in my 2012 Silverado trucks seams to preform better with this rather than the mobile one I was using before

I have used this oil for several years with very satisfactory results. The only drawback is that it is priced in American dollars and starts to become expensive when the exchange rate widens.

GOOD STUFF

From it first oil change I have used Amsoil 5w20 and to this day runs like new. In fact all my engine run in Amsoil products. Very happy with the performance and durability it keeps giving.

This is the Staple in any engines life! Have been using this Amsoil product for 16 years now in many different vehicles. Use Amsoil products in all my equipment, SUV's, cars, lawn tractors and mowers, from the motor oil to the transmission fluid to gear lube/differential. Never have to worry about or even think about if you have the best protection possible. Engines run very clean, smoother, quieter, and noticeably better fuel mileage. Outstanding performance!!!!

A number of years ago I learned that synthetic oil was superior to conventional oil. Shortly thereafter I tried amsoil and discovered that amsoil was superior to other synthetic oils. This became evident when I started traveling on 2250 mile trips on a fairly regular basis. Other synthetics needed a quart on the trip. Amsoil, none. I researched the issue and a competitor alleged that the difference was based upon Amsoil's use of too much of a certain additive and that that additive would ruin a catalytic converter. I have put over 150,000 miles on three different vehicles and none ever needed a catalytic converter or oxygen sensor.

I've used Amsoil products now for about twelve years. After a year, the drain oil is not much darker than it was when it went in. I put about 1000 miles per month on my truck (2014 Xterra). Previously, I drove a 2001 4Runner similar miles.

I've been using Amzoil products in all of my vehicles since 1988.

I come from the old school that good quality oil is always cheaper than rebuilds and parts replacement. I have been using Amsoil products for over 20 years and the results have been outstanding. They provide the best protection against wear keeping the powertrain in outstanding clean and excellent conditions for many, many trouble free miles.

Our 2015 GMC requires GM spec oil which Amsoil more than meets. Being a bit old school on oil changes I like the margin of a high quality synthetic because modern engines are under much higher stresses and heat than when I started driving and wrenching.

I have been using Amsoil synthetic oil since the 70's. This was at the recommendation of my father in law who was a professional master mechanic for a large public utility company. Amsoil synthetic oil and grease has been used in all of my vehicles over the last 40 years without any internal engine failures. Easy starting in below zero winter temperatures without any hammering or pounding noises. For clean and efficient engine performance there is nothing better than Amsoil synthetic products!
